Press Opinions. 



"The work has evidently been prepared with great care, and, as far as we can judge, should 

 be very useful to the dyer and colourist." Halifax Courier. 



"The volume, which is clearly and popularly written, should prove of the utmost service to 

 all who are concerned with the practical use of colours, whether as dyers or painters." 

 Scotsman. 



"To the practical colourist, and also to technical students, Mr. Paterson's new work will be 

 very welcome We are often asked to recommend books on different subjects, and have no 

 hesitation in advising the purchase of the present volume by dyers and calico printers, as con- 

 taining a mass of most useful information at a nominal price." Irish Textile Journal. 



" Mr. Paterson's work not only clearly deals with the theory of colour, but supplies lucid 

 directions for the practical application of the theory. His work will be found exceedingly 

 helpful, not only to the practical colourist, but also to students in our textile colleges, by 

 forming a useful complement to their class lectures. There are several exquisitely coloured 

 plates and a large number of other illustrations of theory and practice in colour blending, and 

 also a series of plates with specimens of dyed fabrics attached, in explication of the author's
